5 volt, A good darkfield image is obtained by reducing the aperture of the objective lens. The def technique is extremely useful in revealing and differentiating objects of very low contrast such as living bacteria, cilia ted and flagellated protozoans, yeasts, etc, and such objects appear brilliantly illuminated against the dark background. The box is in very good condition.
Offered for sale is a near mint condition American Optical Ao Spencer biosphere darkfield condenser, model 218F, with built in and center able illumination. Stained smears of these organisms respond in like manner, and colloidal particles are seen as bright diffraction discs. These transformers not included in this offer are readily available on.
The condenser will fit American Optical Ao Spencer series 2, 4, 10, and 20 microscopes. 7 ampere lamp GE 812, and two double sets of coaxial centering screws. The effect of def microscopy is often described as similar to that of observing stars in the night sky against a nearly black background. The great contrast obtained with def microscopy provides maximum specimen visibility.
The resulting object appears self luminous against a black background, and strikingly beautiful images of high contrast may be obtained. During set up, the large circular knurled knobs are used to the condenser mount, while the smaller cylindrical knurled knobs are used to the built in lamp. The original power cord is included and powers the built in Illuminati using a voltage transformer, such as Ao transformers nos.
Made in the us. A dark field def condenser is used to cause a cone of light rays to strike the specimen from the sides, rather than straight up from below as in normal bright field work. The condenser is in its large original red velvet lined box with snap closure.
This is accomplished either by insertion of a funnel stop into the objective, or by using an objective equipped with an iris diaphragm. All components are in fine condition and appear to have had minimal use. The built in illumination system has been tested, is working, and consists of a center able mount, a separately center able built in light source featuring the original, 651, or.
